Abstract

The invention discloses a slide core pulling structure used for a plastic mold. The slide core pulling structure comprises a slide mechanism: a bottom layer slide seat mechanism is arranged in a mounting groove; a large clip positioning mechanism is arranged between the tail part of the bottom layer slide seat mechanism and the mounting groove; the bottom layer slide seat mechanism is provided with a bottom layer clearance hole and a middle slide seat mechanism; a small clip positioning mechanism is arranged between the tail part of the middle slide seat mechanism and the bottom layer slide seat mechanism; a large clip positioning mechanism arranged between the front end of the middle slide seat mechanism and the bottom layer slide seat mechanism; a middle clearance hole and a top layer slide seat mechanism are arranged on the middle slide seat mechanism; a small clip positioning mechanism is arranged between the tail part of the top layer slide seat mechanism and the middle slide seat mechanism; a top layer inclined guide hole is formed in the middle slide seat mechanism; an inclined guide column is formed in a front mold; and the inclined guide column is arranged in the top layer inclined guide hole, the middle clearance hole and the bottom layer clearance hole. The slide core pulling structure has a simple structure, the quality of a product can be guaranteed and the production cost can be effectively reduced.

Description

technical field [0001] The invention relates to a row-position core-pulling structure for plastic moulds. Background technique [0002] If the plastic mold row position is too deep, such as more than 10mm, the product is easy to be damaged and deformed when the mold is opened. The existing row structure is relatively complicated, which cannot effectively guarantee product quality, and the production cost is relatively high. [0003] Therefore, the existing plastic mold rows need to be further improved. Contents of the invention [0004] The object of the present invention is to overcome the deficiencies in the prior art and provide a row-position core-pulling structure for plastic moulds, which has a simple structure, can ensure product quality, and can effectively reduce production costs. [0005] In order to achieve the above object, the present invention adopts the following scheme: [0006] A row-position core-pulling structure for a plastic mould, comprising a front...
